A juvenile is facing drug charges after police responded to Liberty High School for an emergency medical call late last month and found two people unconscious.

North Liberty police were called to the school at about 11:40 a.m. Nov. 30 for a report of an unconscious individual, according to a statement by North Liberty Police Chief Diane Venenga.

That person, who was 15 years old, regained consciousness and was treated by paramedics and taken home by their parents without receiving additional medical treatment, Venenga said in the statement.

While paramedics were at the school, Venenga said another 15-year-old lost consciousness and was also treated by paramedics. That person also regained consciousness and was released to their parents, the statement said.

Both juveniles who fell unconscious said they had taken a Xanax pill that they bought from another person.

Xanax, the brand name for the drug alprazolam, is a benzodiazepine commonly used to treat anxiety.

Police have charged a juvenile with distributing a controlled substance, Venenga said in the release. She said she could not provide additional details because the person is under 18 years old.
